  • 摘要:Long-term variations (2003–2015) of the Equivalent Water Height (EWH) above the geoid's contour obtained from GRACE satellite measurements are analyzed to establish the relationship between changes in the gravitational field with the stress-strain state of the geological environment and the seismic process in Central Asia (Pamir and Tien-Shan regions). The earthquakes gravitational effects study, based on the use of various GRACE models allows us to distinguish the component of the gravity field, which may be related to seismic activity. The results of temporal and spatial gravitational anomalies identification, the probable causes of which were tectonic factors associated with the redistribution of masses in the lithosphere as a result of large (M>5.5) regional earthquakes, are presented.
